Rated 5 out of 5 by from Peace of Mind! Thank you! Thank you Generac. I installed the 22kw about two years ago after we lost power for a day. Hurricane Florence just devestated NC. We did not suffer any loses but we lost power. The generator came on immediately and ran for two days nonstop. I felt bad for the neighbors in the sweltering heat. My adult children all came and stayed with us and we were safe and happy with full a/c and everything powered on. We watched movies and weathered the storm easily. It was truly amazing. Thank you!!! Best investment I’ve ever made!!

Rated 4 out of 5 by from Saved us during Hurricane Florence This generator was awesome. We lost power for 5 days. We have 200 gallons of propane and did not know how much this generator would use. We would run it for several hours and then turn it off for a few hours. I would leave it off at night. We lost power Thursday at 9 pm. 20 seconds later it cranked up and gave us power. On Monday the propane guy came and fill us up with 67 gallons. I still had 133 to go!!!! I can not imagine ever having a house without a Generac generator. We ran both air conditioner compressors, and everything else. Our internet never went out. Our life was as if we had not lost power. We at times really felt guilty having all the luxuries while other people suffered. Our house was set to 72 degrees and ran both refrigerators too. The only negative I have is the LED quit working. There is only a blank display. I really hope Generac helps me with this issue. It did not hurt the performance during the storm, however; I can not see my hours etc. As a storm Generator, this display should survive. This is the only reason I knocked a star off. Please help a Hurricane Florence survivor out.

Rated 5 out of 5 by from Rated #1 by Consumer Reports The product was everything it was purported to be. Very satisfied with Generac, have a 12000 watt generac portable for on the job backup also. However be careful who you purchase from. Norwall power systems. uploads your order stating that additional shutoff switches are required (2) due to NEC Requirements. Additional costs $35 ea. For a total of $70.00 When shown that their rep. was in error, after delivery. you are told you will have to pay return shipping and an additional 20% restocking fee, with pictures and additional stipulations that are not consumer friendly. Read their return policy. there is no customer service.

Rated 5 out of 5 by from Great Unit After just getting through Hurricane Florence, our power was out for 33 hours. This unit made us feel guilty of having non interrupted power to our home without limitations. Thank you Generac!!

Rated 5 out of 5 by from My Generator Excellent product. From power off, generator starts in 7 seconds. 15 more seconds go by, and power is applied to the home. We are very happy with this.
